FMF Power Core IV

Comments On Jan 05, 2016:This exhaust along with a K&N filter provided a very noticeable increase in performance. Installed the carb jets recommended by FMF and after a few adjustments it was up and running. This exhaust is much louder than the stock exhaust and sounds incredible. Definitely worth the money.

Ronnie Mac approves!

Comments On Sep 30, 2015:Its a long bumpy road trying to find the perfect pipe for your bike. Some are too quiet, some are rip your face off loud.... Others can sound like a bad day in the office restroom. This FMF powercore IV S/A Silencer hits that sweet spot... The exhaust note this baby puts out will have you twisting throttle more and making excuse to the wife just go hear it idle. I loved my FMF slip on, The Quality and fitment were spot on! clamps fit well and nothing ever loosened up on me. I got real cray and removed the S/A and threw on a FMF Powerbomb head pipe. the Sounds my machine produced were mind blowing. pretty much the greatest thing these ears have ever heard. Support FMF support RMATV and DO NOT HESITATE to order this slip on.

Stop debating buying the Power Core 4- JUST DO IT!

Comments On Aug 27, 2015:I spent a good week reviewing website reviews, watching You Tube videos, talking to dealers, etc. There are several options and manufacturers dealing with after market exhaust. The FMF Power Core 4 is absolutely AWESOME. The videos do not do justice to the sound this thing puts out! It went from sounding like a kitten to an angry lion in about 20 minutes of EASY installation.
However, don't expect this to totally give you balls to the wall power. It did increase the performance somewhat and I am very pleased. The immediate change was just the awesome sound and rumble this thing puts out. My TTR is now as loud, or louder, than my brother's YZ!
Highly recommended!

Comments On Jun 30, 2015:I just put the fmf power core 4 on along with the fmf power bomb header and I am amazed with the the difference in power! Very very snappy throttle response and great low to mid range power and even in the top end it is great! Can hardly keep the front tires on the ground!!

Dont ride without it.

Comments On Mar 22, 2015:This pipe is essential. Combined with a powerbomb header, dave's mod, and some new jets get the best out of the old red drag. Sounds beastly too!
